Iran Closes Strait of Hormuz to All Vessels Following US Strikes

Impact verdict

High impact. Loss pathway: A named closure of the Strait of Hormuz — carrying a significant share of global oil and major LNG flows — directly following US strikes is a concrete maritime and energy disruption. Reports of kinetic threats to transiting vessels, a reported second strike on the US Fifth Fleet base in Bahrain (per the originating event record), and hundreds of reportedly stranded ships elevate war-risk and political-violence overlays and support repricing of Persian Gulf transit books. Corroborating reports that even declared reopenings may not immediately restart commercial traffic reinforce Marine Hull, Marine Cargo, Marine War, Energy, Political Risk/Political Violence, and downstream treaty exposures. Evidence is mainstream-media sourced; reported crude flow figures, stranded-vessel counts, and operational signals do not by themselves force an insured severity band. Limits: enforcement scope (commercial vs. military), duration, treatment of in-transit traffic, naval posture, US/coalition response, and any insured industry loss figure remain unconfirmed. The signal warrants elevated war-risk, political-risk, and energy vigilance pending confirmation.
